We provide a dynamically downscaled and bias corrected dataset at 3 km horizontal resolution over the U.S. Midwest, covering the period 1951-2100 under historical and RCP8.5 conditions. Data is produced using a regional model (WRF 3.9), driven by NCEP/NCAR reanalysis 1 and CESM1 simulations designed for downscaling with WRF. Data provided includes temperature (T2) and precipitation (PRECIP). This is associated with Lauer et al. (2022).
